PUMP MECHANISM.

Application filed. June 4, 1925.

The main object of this invention is to provide a mechanism for reciprocating the piston of a pump so that water can be drawn thru a pump from a subterranean level.

The device is actuated by a source of power and consists of a pendulum which arcuately swings the geared disk, the geared disk being in mesh with the rack bar mounted onthe top of a pump piston to accomplish a reciprocating motion of said piston.

Another object is to provide mechanism for reciprocating a piston pump consisting of a pendulum operated swinging gear disk which has an equalizing weight thereon adapted to be adjusted to various positions on the pendulum.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a front elevational view of the mechanism.

Figure 2 is a side elevational view of the same. I

Figure 3 is a sectional elevational view thru the pendulum weight, showing the means of securing the same in various positions on the pendulum.

Figure 4 is a side elevational view of Figure 3.

Referring in detail to the drawing, the numeral 10 indicates the stands or legs upon which a frame 11 is mounted. The side portions of this frame 11 support a pair of journal straps 12 and 13 which are mutually spaced-apart and are adapted to saddle a shaft 1 1 on which a disk 15 is secured. Around a portion of the periphery of the disk, teeth 16 are formed which mesh with a rack bar 17 guided vertically in a sleeve bracket 18 which is fixed to the frame member 11 adjacent to the disk 15. The lower end of the rack bar 17 is integral with a pump plunger 19 which is adapted to re ciprocate in a cylindrical pump 20 which has a spout 21 near its upper end. The disk 15 has a vertical pendulum bar 22 secured thereto, the pendulum being mounted on the disk by rivets or any other desirable means. This bar extends vertically downward and has a stud 23 projecting from its side which is engaged in an eccentric channel 241 formed in a sheave wheel 25. Said sheave wheel is mounted on a shaft 26 which is rotated by a source of power not shown in the drawing,

as a motor or the like, and is supported in a bracket 27. 7

One edge of the pendulum bar 22 has V shaped teeth 28 formed thereon. Before the device is assembled, that is, the sheave wheel mounted in place adjacent the stud, a hollow weight member 29 is slipped over the pendulum bar. This weight member has a vertical channel 30 passing therethru and in which the bar 22 is movable. On one of the side walls of the weight member 29, a slot 31 is formed and on both sides of this slot, raised lugs 32 are provided in which the spindle 33 of an eccentric plate is mounted. This eccentric plate is adapted to engage the side opposite to the teeth 28 of the pendulum bar and urge said bar against the opposite wall of the reight member on which are formed a pair of spaced-apart teeth 35.

The device is adapted to reciprocate the plunger 19 of the pump in order to draw water to the spout 21 from a subterranean level. The usual pump mechanism is used within the casing 20 and the upper end of the plunger is connected to the rack bar or may be integral therewith. The sheave wheel 25 in rotating, causes the pendulum bar 22 to be moved thru a radial arc owing to the stud 23 being engaged in the eccentric channel 24 of the sheave wheel 25. This pendulum bar 2 being connected to the disk 15 arcuately rotates the latter and as the same is in geared mesh with the rack bar 17, the latter will be reciprocated vertically to lift and lower the pump plunger 19. To compensate for light or heavy drawing of the plunger accordingly as the well is nearly full or nearly empty, a weight member is provided. This weight member may be adjusted to various positions lengthwise on the pendulum bar by rotating the eccentric plate 34 which in the position indicated in Figure 3, shows the weight locked in place on the pendulum bar. To release this weight so that the same may be adjusted to another position, the pro jecting portion of the eccentric disk 3% is rotated so that the periphery of the eccentric plate which is farthest removed from the rotational axis, is shifted to the position where it projects from the side of the weight member, thus permitting the weight to he slid transversely on the pendulum bar so that the teeth 35 formed on the weight member will be disengaged from the teeth 28 formed on the pendulum bar member 22, thereby disengaging the pendulum bar from the Weight so that the latter may be moved to a new position.

I claim 1. In a device of the class described, a pump casing and a plunger slidable therein, a rack bar mounted on said plunger, a toothed disk engaging said rack bar, a pendulum extending downwardly and mounted on said disk, said pendulum being adapted to partly rotate said disk and reciprocate the plunger, a sheave wheel adapted to actuate said pendulum, an eccentric channel formed in said sheave wheel, a stud on said pendulum engaged in said channel, said sheave when rotated causing the eccentric channel to arcuately swing said pendulum, and a weight adjustablymounted on said pendulum.

2. In a device of the class described, a pump casing and a plunger slidable therein, a. rack bar mounted on said plunger, a toothed disk engaging said rack bar, a pendulum extending downwardly and mounted 011 said disk, said pendulum being adapted to partly rotate said disk and reciprocate the plunger, a sheave wheel adapted to actuate said pendulum, an eccentric channel formed in said sheave wheel, a stud on said pendulum engaged in said channel, said sheave when rotated causing the eccentric channel to arcuately swing said pendulum, a weight adjustably mounted on said pendulum comprising a hollow member slidable on said bar, said pendulum having teeth on one of its sides, teeth on said weight member adapted to engage the teeth of the pendulum, and an eccentric plate pivotally mounted on said weight member whose periphery is adapted to engage the side of the pendulum in one position and lock the teeth of said weight member in fixed position between the teeth on the pendulum member to secure said weight member in position on the bar.

3. In a device of the class described, a pump casing and a plunger slidable therein, a rack bar mounted on said plunger, an annular disk having teeth on its periphery en gaging said rack bar, a pendulum extending vertically downward and mounted on the side of said disk, a sheave wheel adapted to swing said pendulum, an annular channel formed eccentrically on the face of said sheave wheel, a stud on said pendulum engaged in said channel, said sheave wheel when rotated causing the eccentric channel to arcuately swing said pendulum, and a weight slidably mounted on said pendulum and cooperative means on the pendulum and weight for fixing the latter in any position on the pendulum thruout the length thereof.

In testimony whereof I atiix my signature.
